The bolt pattern for the Audi A4 is 5x112 mm across most modern generations. In practice, this means five lug holes arranged around a 112-millimeter circle. Always verify for your exact year and model, but 5x112 is the standard.
Over its years, the A4 has kept a consistent lug configuration, which helps when swapping wheels with other Audi or VW Group models. The center bore is typically 66.6 mm, and many wheels from related Audi models share the same bolt pattern, simplifying compatibility for owners upgrading or replacing wheels. However, regional variations or specific trim-level wheels should be double-checked in your owner’s manual or with a dealer for absolute certainty.
Bolt pattern basics for the Audi A4
The following quick details cover the core pattern you’ll most often encounter on A4 models. This can help you assess wheel and brake compatibility before making a purchase.
- 5x112 mm bolt pattern (five lug holes on a 112 mm circle).
- Five-lug configuration is standard across most generations of the A4.
- Center bore is typically 66.6 mm, which is important for hub-centric wheels or the need for spacers/rings.
- Pattern is shared with many other Audi and VW Group models, aiding cross-model wheel compatibility.
Knowing these basics helps you determine whether a wheel or adapter is suitable for your A4. It also explains why many aftermarket and OEM wheels advertised for Audi or VW Group vehicles often fit the A4 without modification.
How to verify wheel compatibility for your A4
When shopping for wheels, always confirm the exact fit for your vehicle year and trim. Use these steps to verify compatibility before purchase.
- Check your owner's manual or the driver-side door jamb sticker for official bolt pattern, center bore, and lug nut specifications.
- Match the wheel spec to the vehicle: 5x112 bolt pattern, 66.6 mm center bore, appropriate wheel width and offset.
- If buying aftermarket wheels, ensure they are listed as compatible with Audi A4 and check for hub-centric rings if the wheel bore differs from 66.6 mm.
- Avoid mixing incompatible patterns (for example, wheels labeled 5x100 on an A4 expecting 5x112) unless you use proper adapters or select wheels specifically rated for 5x112.
To avoid surprises, consult a dealer or a qualified tire/wheel shop, especially if you plan to mix wheels from different generations or models within the Audi lineup.
Generation-by-generation notes
B5 generation (1994–2001)
The early A4s in the B5 family used the same general 5x112 bolt pattern with a 66.6 mm center bore, aligning with later Audi models for wheel compatibility.
B6/B7 generations (2000–2008)
During the B6 and B7 eras, Audi maintained the 5x112 bolt pattern, making wheel exchanges with other modern Audis straightforward, though always confirm the exact bore and offset for specific trims.
B8/B9 generations (2008–present)
From B8 onward, the A4 continued with 5x112, solidifying cross-compatibility with numerous Audi and VW Group wheels. The center bore remains around 66.6 mm, with standard lug configurations kept consistent for ease of replacement and upgrades.
Summary
In short, the Audi A4 uses a 5x112 bolt pattern across most modern generations, with a 66.6 mm center bore and five-lug configuration. This consistency aids wheel swaps and cross-model compatibility within the Audi and VW Group family, but always verify your exact year, trim, and wheel specifications before purchasing new wheels or adapters. When in doubt, consult your owner’s manual or a qualified wheel specialist to ensure a proper, safe fit.
